Answers

Answer 1

Convenience sampling is commonly used in the later stages of research and it is a time-consuming process if there is a large number of respondents. So the option 3 ad 5 is correct.

In the given question we have to check which of the following is true of convenience sampling.

The given options are:

It allows researchers to measure the representativeness of a sample. It allows researchers to generalize the data collected to a defined target population.It is commonly used in the later stages of research.It is a nonprobability sampling method.It is a time-consuming process if there is a large number of respondents.

Convenience sampling is a non-probability sampling process-based sampling technique.

When sampling vast amounts of data, it is helpful and takes less time.

It prevents the researchers from determining the representativeness and is not appropriate for earlier stages of research.

Additionally, it prevents researchers from extrapolating the data they have acquired.

Hence, convenience sampling is commonly used in the later stages of research and it is a time-consuming process if there is a large number of respondents. So the option 3 ad 5 is correct.

Answers

The cost of the car for the year is $3800 for Nerida Kyle and it will cost less than lyft.

The cost of the car for the year will be calculated based on the amount she will spend in total on the car. The formula to be used is -

Total cost = Cost price of the car - Selling price

Cost price of car will be sum of all the expenses, calculated as follows -

Cost price of the car = 15000 + 1200 + 800 + 300

Performing addition on Right and Side of the equation

Cost price of the car = $17,300

Total cost for the year = 17,300 - 13,500

Performing subtraction on Right and Side of the equation

Total cost for the year = $3,800

Hence, Nerida Kyle will spend $3,800 on car which is better than lift.

Answers

Answer:

The numbers are 10 and 21.

Step-by-step explanation:

x + y = 31

xy = 210

x = 31 - y

(31 - y)y = 210

31y - y² = 210

y² - 31y + 210 = 0

(y - 21)(y - 10) = 0

y - 21 = 0  or  y - 10 = 0

y = 21  or  y = 10

The two real numbers are 10 and 21.

What is a quadratic equation?

Quadratic Equations are algebraic expressions of degree 2 in one variable and are of the form ax² + bx + c = 0.

In simpler terms, a quadratic equation is be defined as a polynomial equation of degree 2.

Given that, there are two real numbers with a sum of 31 and a product of 210.

We need to find their values using the concept of quadratic equation,

So, according to the question,

x + y = 31 (eq 1)

xy = 210 (eq 2)

x = 31 - y

(31 - y) y = 210

31y - y² = 210

y² - 31y + 210 = 0

(y - 21) (y - 10) = 0

y - 21 = 0 or y - 10 = 0

y = 21 or y = 10

in order to test if the mean from population a is greater than the mean from population b what kind of t-test would you use?

Answers

According to the given statement the option B and C are correct:

b) unpaired t-test

c) one-sample t-test

Briefing:

We will apply an unpaired test in this situation because both populations are independent and unrelated to one another, making it impossible to pair the data from the two populations.

Consider the statement, "The mean from population A is bigger than the mean from population B," for example. This suggests that we'll utilize a single-tailed, unpaired test. Therefore, option d and b may be the best pairing.

What exactly is a one-sample t-test?

To ascertain whether an unknown population mean differs from a given value, the one-sample t-test is a statistical hypothesis test.

What distinguishes a t-test with one sample from one with two samples?

The t-value is calculated using your sample data from the two groups and the 2-sample t-test. The procedure is quite comparable to the 1-sample t-test, and the signal-to-noise ratio can still be compared. The 2-sample t-test necessitates independent groups for every sample, unlike the paired t-test.

Answers

Option B is the correct answer, The set of correlations which correctly shows the highest to lowest degree of relation is -0.91, +0.83, +0.10, -0.03.

What is correlation?

In statistics, the correlation is a technique used to determine the relationship between the two variables. The correlation's range is from -1 to +1. There are three primary categories of correlation: no correlation, positive correlation, and negative correlation. When the correlation value is zero, there is no association; the correlation value that is closest to zero indicates the weakest degree of relationship.

We must select the set of correlations in the question that accurately displays the highest to the lowest degree of relation.

Option B is the best choice since we must take the absolute value into account in order to determine the relationship's degrees. Here, the absolute values drop from 0.91 to 0.03.

Option A is incorrect since the absolute values decline from 0.91 to 0.03 and then climb to 0.10 in this situation.

Because the absolute values are not listed in decreasing order, Option C is incorrect.

Because the absolute values in this situation are not ordered in decreasing order, Option D is also a incorrect choice.

Therefore, option B, is the correct option.

a single player is dealt 8 cards from a standard 52 deck what is the probability that the 5th card was the htird and last jack dealt

Answers

The probability that the 5th card was the third and last jack is 0.016%

How to calculate the probability of cards?

Standard card deck only have 4 jack cards and 48 other cards is not a jack. So, to calculate the probability is simply by dividing the number of favorable outcomes by the possible outcomes.

It is very important to note, wherever the first and second jacks are located it will not affect the calculation for the third jack.

So, you can calculate with this formula,
P(5th card is third and last jack) = (48/52)×(47/51)×(4/50)×(3/49)×(2/48)×(46/47)×(45/46)×(44/45)

or this formula,

P(5th card is third and last jack) = (4/52)×(3/51)×(48/50)×(47/49)×(2/48)×(46/47)×(45/46)×(44/45)

After we simplified calculation, we get

= (4 × 3 × 2 × 44) ÷ (52 × 51 × 50 × 49)

= 0.00016 or 0.016%

Thus, the probability is 0.016% for the third and last jack on 5th card.

Now we try to express s as h and r. Denote the points where the incircle meets the triangle as X,Y,Z, where O is the incenter, and denote AX = AY = z, BX = BZ = y, CY = CZ = x. Since XOZB is a square (tangents are perpendicular to radius), r = BX = BZ = y. The perimeter can be expressed as 2(x+y+z), so the semiperimeter is x+y+z. The hypotenuse is AY+CY = z+x. Thus we have s = x+y+z = (z+x)+y = h+r. The answer is (B) 3,14r/h+r

The ratio of the area of the circle to the area of triangle is πr : h+r.

We know that rs = A

where r is the radius , s is the semi perimeter and A is the area.

We have that the ratio of the area of the circle to the area of the triangle is

πr²/rs = πr/s.

Now we will express s as h and r. Denote the points where the in-circle meets the triangle as X,Y,Z where O is the in-center and denote

AX = AY = z, BX = BZ = y, CY = CZ = x.

Since XOZB is a square

Therefore r = BX = BZ = y.

The perimeter can be expressed as 2(x + y + x), so the semi perimeter is

x + y + z.

The hypotenuse is AY + CY = z + x.

Thus we have s = x + y + z

                          = (z + x) + y

                        s = h + r

Therefore the ratio of the area of circle to the area of the triangle will become πr : h+r.

can someone explain how to do this with the answer pls

Answers

Answer:

x = 23

Step-by-step explanation:

The sum of two interior angles is equal to an exterior angle that is supplementary to the third interior angle.

We can write the following equation based on this information to find the value of x:

2x + 3 + 51 = 100 add like terms

2x + 54 = 100 subtract 54 from both sides

2x = 46 divide both sides by 2

x = 23

Factor out the greatest common factor. If the greatest common factor is 1, just retype the polynomial.

Answers

Using the definition of divisibility, 2p is the greatest common factor.

In the given question we have to factor out the greatest common factor. If the greatest common factor is 1, just retype the polynomial.

The given polynomial is 2p^3+6p.

Now taking 2p common from both terms

=2(p^2+3)

By the definition of divisibility, we get

2p | 2p^3 and 2p|6p, 2| 2p^3 and 2|6p also p|2p^3 and p|6p.

So, 2,p and 2p are common factors of 2p^3 and 6p.

Hence, 2p is the greatest common factor.
